Yes -- have you not seen the size of SD cards these days? An R for
Windows install is under 50Mb and needs about 12Mb RAM to run.

That was not the question.

But that was. However, as I said, you would have to find a suitable
compiler or cross-compiler, that supports enough features (and I suspect
IEEE arithmetic would be a problem, especially as it is for VC++ on full
Perhaps you would like to write such a compiler, as technically there's
not much to stop you?
